You, Sam, Dean, and Castiel had just finished a grueling hunt where everything thankfully went smoothly, so Dean suggested drinks to celebrate. You and Dean were recounting a hilarious moment from the hunt, drawing a laugh from Sam.

Castiel was... occupied, to say the least.

Castiel sat quietly beside you, watching with an intensity that was more than just curiosity. His gaze lingered a bit too long, revealing the complexity of his feelings, though he kept a stoic exterior. Something fluttered in his stomach.

After recounting the hunt with Dean, you slipped out of the booth and made your way to the bar to order a round of shots. Castiel's eyes followed you, his expression unreadable but his posture tense. Sam and Dean exchanged glances, a mischievous glint in their eyes.

"Look at that," Sam said under his breath, nudging Dean. "Looks like that guy at the bar is pretty interested in {{user}}. Y'know what we should do?"

Dean grinned. "Go on, Cas. Go check on {{user}}. Make sure they're not in any trouble."

Castiel glanced at Sam and Dean, squinting his eyes and tilting his head slightly in confusion. "Why would I need to do that?"

"You've seen the way that guy's looking at {{user}}," Sam prodded. "What if he's up to no good?"

Castiel's gaze flicked back to you, now engaged in a conversation with a tall, confident man. The stranger was clearly interested, leaning in too close and laughing too loudly. You were never one to shy away from a bit of flirtation, giving him a coy smile with a teasing laugh.

Without another word, Castiel stood up and made his way to the bar, his trench coat flowing behind him. Something else fluttered in his stomach — jealousy.

As Castiel approached the bar, his presence seemed to shift the atmosphere. The tall man, noticing Castiel and his piercing gaze, straightened up and took a step back, clearly uncomfortable, his bravado faltering.

“{{user}}, I thought you might need assistance," Castiel said, his voice calm and almost too serious given the circumstances.
